Eagle Chevy 502 4.375in Counterweight Crank 6.535in H-Beam 40cc 4.600in Pistons Rotating Assembly

Eagle has a solid reputation for building tough engine components, and this rotating assembly is a prime example of their commitment to strength for demanding applications. If you're building a high-performance Chevy 502 for serious competition, whether it's running exotic fuels, heavy nitrous, or high boost, this assembly is designed to handle it.

At the heart of this package is a 4.375-inch forged 4340 steel crankshaft featuring center counterweighting. This design helps to balance the rotating mass more effectively, reducing stress on the engine's main bearings and improving overall durability under extreme loads. Paired with the crank are 6.535-inch H-beam connecting rods, known for their strong I-beam cross-section and ability to withstand high horsepower. These rods come equipped with 7/16-inch ARP L19 bolts, a high-strength fastener specifically chosen for their ability to maintain clamping force under extreme cylinder pressures.

The pistons are forged 2618 aluminum from Mahle, featuring a 40cc dome volume and a 4.600-inch bore size. This dome shape is designed to work with specific cylinder head combustion chamber volumes to achieve your target compression ratio. The assembly includes plasma-moly file-fit piston rings, allowing you to precisely gap them for your specific application, which is crucial for optimal sealing and performance in a competition engine. Finally, King XP series rod and main bearings are included, offering enhanced durability and lubrication for high-stress operation.

This rotating assembly is a comprehensive package for a serious engine build. Please note that this assembly is not CARB approved and cannot be shipped to California. Always refer to manufacturer instructions for proper installation and break-in procedures.
